Gelatin-Based Films and Coatings for Food Packaging Applications

TLDR

Gelatin, a collagen‑derived biopolymer with versatile technological properties, is widely used across industries and is increasingly enhanced with additives to improve food preservation, especially for meat and fish products. The review examines recent advances in the composition of gelatin‑based edible films and coatings, including nanoparticle additives, and evaluates their properties for food packaging applications. The review details the use of antimicrobials, antioxidants, and other agents—including nanoparticle additives—to enhance gelatin films and coatings, driven by consumer demand for healthier food preservation and extended shelf life.

Abstract

This review discusses the latest advances in the composition of gelatin-based edible films and coatings, including nanoparticle addition, and their properties are reviewed along their potential for application in the food packaging industry. Gelatin is an important biopolymer derived from collagen and is extensively used by various industries because of its technological and functional properties. Nowadays, a very wide range of components are available to be included as additives to improve its properties, as well as its applications and future potential. Antimicrobials, antioxidants and other agents are detailed due to the fact that an increasing awareness among consumers regarding healthy lifestyle has promoted research into novel techniques and additives to prolong the shelf life of food products. Thanks to its ability to improve global food quality, gelatin has been particularly considered in food preservation of meat and fish products, among others.
